of the rectum, rvlürns short, curved, and descending, duodenum more or less 

 widened, with three or four pyloric tutes, the shortest of them is at the 

 anterior side, and tlie longest is furthest removed from the i^ylorus. Intestine 

 is naJTOW and straight. Air-bladder long, more or less spindle-shaped, 

 running the whole length of the abdominal cavity. Urinary bladder is 

 very long and is fouud attached to the ventral wall of the air-bla,dder, 

 and above the rectum in the abdominal cavity. Two ureters unite to a 

 median canal near the end of the blended kidneys, and open to the posterior 

 end of the bladder. 



This species is found chiefly in the clear warm water of the tropical and 

 subtropical seas, and is found at the mouth of Tokyo Bay in the east, from 

 Shimane-ken, Kyoto-fu, and at the north of the southern coast of Chosen. A 

 few examples are nearly always found in the markets of southern Kyushyu in 

 summer and autumn. In the Ogasawara Islands this fish is cut iutD pieces 

 and dried after boiling, or is preserved in hermetic cans. 



Pelagic fish, do not make a school. They feed on pelagic fish and 

 calamaries. Voracious and easily attracted with natural or artificial baits. 

 Caught with trolling lines, which are dressed with live or salted saurel, or with 

 spears after alluring with artificial fish, made of wood cr canvas to imitate 

 flying fish or its own species. In Kochi-ken and Kagoshima-ken the fish is 

 atti-acted to the shade of a large bimdle of liamboo stems or branches of some 

 light wood, moored in oS'-shore grounds, specially construct«;d for the pm-pose. 



The colour of the fisli is steel-blue in the back, with about thirty dark 

 ti'ansverse bands, which are distinct in young fishes, ;uid in the adult fish 

 when excited. Doi-sals, pectorals, and caudal .we IJaekish, while the ventraJs 

 are dusky. 



A fish about one and half metres in length, and about seventeen kg in 

 weight, caught off Hachijoshima in June contained nearly ripe ovaries. Another 

 fish of similar size, caught ofi' the Ogasawara Islands in August, 1919 coutiuued 

 much more slender ovaries than the preceding. An immature fish, 28 cm in the 

 total lenghth was caught by a bonito-angler off D^üozaki, Miyckcn ou Aug. 19, 

 1917. 



When speared the fish daa'ts against the bottom, and then flo.its to the 

 surface dead.
